Termcap needed for tektronix 4025

(What is this doing in comp.unix.questions?  It belongs in comp.terminals.
However, followups are now unlikely, so I have not redirected it there.)

Indeed.  I have another 4025 termcap, but yours should do the job.

Note that the one completely impossible `feature' of the 4025---there
is no workaround, short of rewriting the ROM code---is that it confuses
keyboard input with computer input during `escape' sequences.  That is,
if the computer sends

	^]rig 23\r

to send the cursor right 23 characters, and you happen to press the `l'
key while that sequence is working its way across the RS232 cable into
the 4025, the 4025 will imagine that the computer sent something like

	^]rlig 23\r

which either has no effect, or else prints `rlig 23' (I cannot recall
which).

This `feature' causes trouble more often at low baud rates%, so it is
best to keep the 4025 connected at 9600 baud (although it can only
write characters to the screen at around 400 per second, it uses all
available memory for incoming data, so flow control is rarely a problem).
-----
% At 1200 baud, an 8-character sequence takes .067 seconds, giving an
  `error window' 8 times larger than at 9600 baud (.0083 seconds).
